Pneumatic vehicle tires

To solve dieaar task "form according to the invention the threads or wires of the crown ply at the edges of this location with the adjacent Oordfädenabsohnitten the carcass right or approximately right angle _o

In order to achieve this goal, the thread or wire sections of the carcass are curved in the transition area between the running strip zone and the tire sidewalls, and the threads or wires of the zenith layers are preferably also in the area of the edges of these layers facing the tire In this way the above-mentioned angular position is achieved although the threads or wires both on the carcass and the layers in the tread form an acute angle and they essentially fit or wires on the carcass in the tire sidewall describe a right angle with the tire circumference »

The invention can.au.ch is used in such tires of the type mentioned at the beginning '' with - those in the Laufatrelfenzone further zenith positions are provided, the threads or wires of which in the direction of the carcass threads or wires adjacent to them run »in order to achieve a further reinforcement in the tread zone. In addition, in the tire sidewalls additional parallel wires or wires are arranged

Further details of the invention are based on the drawing explained «in which an example of execution is shown. It demonstrate:

Fig. 2 shows a partial plan on the lines according to Figure 1 * with the wedge body with the embedded reinforcement inserts is placed in the drawing plane for reasons of better representation. .

The hoop body made of rubber or the like has a a carcass consisting of 1 ply, one on top of the other parallel high-tensile threads 2 running through Wülst'fcu bead out and by looping around the bead cores 3 in the Eeifen

4 beads are anchored. The threads 2 run in the area of the tire sidewalls 5 approximately at an angle of 10 to 15 ° to the Relfenciuerrlichtung, namely when looking at the both tire sidewalls 5 gleioheteigehd, so in the same Oblique orientation. In the transition area between the tire sidewall 5 and the tread zone 6, the threads 2 are arranged in a curved manner. The curved ones ™ Thread sections are marked with 7 «These go over into Stretched thread sections and the threads 2 located here describe with the tire circumferential direction Angle of about 5 to 30 °, but preferably angle of about 20 ° · The section of width of the carcass in which the threads running in a straight line in the tread zone 6 »has a Width to "approximately equal to the width of the tread 8 is.

Above the carcass 1, three zenith layers 9 »10 and 11 are arranged. The threads 12 of these zenith positions are alternately left and arranged rising to the right, the threads 12 of the zenith layer 9 crossing the threads 2 of the carcass 1 and all threads 12 just like the thread sections of the threads adjacent to them, angles of about 5 to 30 °, but preferably about "angles of including about 20 ° with the helical circumferential direction

Ba die leaden 2 in the Heifenseitenwalls 5 untej? a great one Y / inches are arranged to the tire transverse direction are additional! oppositely rising, parallel tensile strengths I have 13 stores! the üagen 14 ers they formed stretch over the entire height of the hoarfrost on the clay walls 5, and their ligaments are - covering the tire shoulders <~ guided between the side layers 10 and 11.

For the prescribed pneumatic tires, it is of particular importance that, in order to achieve a favorable load, for example in the area of the tire shoulders or in the area of the transition points between the cenities of one and the other in the tire sidewalls 5, there is a special laying of the threads or wires carried by the power transmission through the eo 2enitlagen 9 _e 10 and Ii to decrease gradually to their Ründern "These Maßnahiiea: beaietea to ääbei to such threads or .Drähtei the aufgruaä ihr®ä" normal course in opposite directions obliquely aiisteigend in DSII Raifenkörper are embedded, i.e. on the thread 2 of the carcass. 1 on the one hand and the oppositely rising threads 12 of the 2enit layers 9 on the other hand and τ / on to the threads 14 of the 13 and the 2enit layer 10 located herebelow

In order to achieve the vorfceso & risberie effect, the dimensions 12 form the zenith position 9. the edges of this layer with the below befind High curved Fadenabsohnltten d 7 angle of about 80 ° to 90 ° "Meaee is nicnt only by an appropriate curvature of the Eadenabaehnitte 7, eondern also daduroh eri * calibrates _s that the threads 12 'as indicated at 15 , acid tire quality are turned towards »

The threads 12 of the ply 10, on the other hand, show a course which corresponds to that of the threads 2 of the carcass 1 in the adjacent sections. On the other hand, the 3? Eddies 14 of the layers 13, which traverse the Iteifenöeitenviände 5, immediately above this are bent in such a way that the oblique angle of their shops is enlarged so that a crossing angle A of about 80 to 90 arises here too.
